COMBINED SHOCK-COMPRESSING AND NEEDLE-SHOCK-ABSOBBING MEANS FOR GRAIN SHOQCKEB SQ Application filed August 18, 1324. Serial 1%. 732,594.

The present invention relates to grain sliiockingmachines,andparticularly to the binding mechanism therefor, having improved meansassociated with the vusual needle thereof for uniformly compressing theshock while the same is being bound with twine in the shock formingreceptacle, the same means being adapted also to counterbalance theweight of the needle and prevent hammering and vibration thereof afterthe same has moved to inoperative position, when the shock tyingoperation has been, completed and theshock has been rearwardly dumped onthe ground.

An object of the invention is to provide a simple and efficient selfacting means cooperating with the needle for compressing.

the shock during the binding operation, the same means being adapted toperform the dual function of serving as a shock absorbing andcounterbalancing means vfor the needle whe it is movedto normalinoperative position.

A further object is to provide a mechanism of the above character whichmay be utilized on existing standard type grain shockers without thenecessity of greatly modifying its construction and at a minimum ofcost. I

These objects are attained by the im prove mechanism of the.presentinvention, the preferred embodiment of which will be hereinafterdescribed and which has been illustrated in the accompanying sheet ofdrawings wherein Fig. 1 is a rear elevational view of a grain shockerembodying in its construction the improved shock compressing and needlebalancing and shock absorbing means; and

Fig. 2 is a side elevational view of a detail showing the needlemounting and its associated mechanism. a

The grain shocker shown is of the standard type embodying an upwardlyand reara y ump ng, no a y p s a e, sh ck forming receptacle 1O pivotedat its rear d a 11 o e r n rse turp nt ne am mem 2I ar e e Wheeled ram13- h suppo in frame i ms vided with the upright standards 1ft and 15,the standard 15;" on the knotter side ,of the r cep a le upper n the cove t ona lot t-ed-kn ttenb east p ate 1.6 which .c aperates 20 whichoperates the usual knotter mutilated gear wheel 21 operatively connectedby means of the drive chain 22 to a suitable source of power 23.

The knotter shaft 20 has keyed thereto at its rear end a laterallyextending arm 24 which in its rotation carries the arm with it, and,through the medium of the link 25, rocks rearwardly the crank 26carrying a roller 2-7 at its forward 'end which pushes upwardly on thereceptacle l01to dump the bound shock in the field. Keyed or other- Wisefixed to the forward end of the knotter shaft is another laterallyextending arm 28 to which is pivotally connected the pitman 29. Theother end of the pitman is pivoted to a depending arm formed as anintegral part of a quadrantalgear 3O supported for rocking movement" ona shaft carried in a bracket 31 mounted on the standard 15. Thequadrantal gear meshes with a quadrantal pinion 32 keyed to the needleshaft 18 for operating it and the needle, of course, with it.

The improved mechanism of this invention comprises a resilient andflexible element carried by the needle and the frame of the shocker foruniformly compressing the shock during the tying thereof, the sameelement serving to absorb vibration and shock of the needle upon itsreturn movement to normal inoperative position. The structure justreferred to includes the coil spring 33 pivotally connected at one end.to the arcuate needle, substantially midway between its ends, by meansof the eye member 35L, the other end being hooked into a chain 35whichhas its end fastened tlo'lthe standard 15 by means of apifn 36positioned some distance'below theneedle shaft .18.

la e op rati of the grain shocker the power source 23 is tripped intooperation by the conventional sheaf delivery fork (not shown) after apredetermined number of sheaves has been piled up in" the receptech;.10, The .knotter shaft 20 is thus re? tated and with it the usualknotting mechanism, the needle 17 in the meantime having been rockedinto cooperative position with the knotter to tie the bundles in thereceptacle into a shock. While the needle is in this tying position thespring 33 exerts a uniform compressing action on the shock, therebyassisting materially in the formation of a stable shock and one whichwill better stand in the field when dumped. The knotting operationhaving been completed, the knotter shaft continues to rotate carryingwith it the arm 24, and, through the connections 25, 26 and 27, dumpsthe receptacle rearwardly to discharge the shock. The needle, of course,is thereupon rocked laterally to inoperative position as shown in dottedlines in Fig. 1, the spring 33 acting to counterbalance its weight andprevent hammering and vibration thereof after it has been thrown back.It has been found desirable to bolt a lug bracket 37 to the uprightstandard 15 to be engaged by the chain 35 to receive the force of thespring 33 when the needle is thrown back.

From the above description it should be clear that this device achievesall of the objects mentioned at the start of this specification, andthat the same is of simple construction, yet dependable in action, andis Well adapted to meet the exacting conditions of hard practical use.

It is to be understood that various changes in form, constructlon, andarrangement of parts may be made by those skilled in the art withoutdeparting from the spirit of the invention as claimed.
